,To all whom/,it may concern.-

lic of Brazil, residing at 31 Rua General Camara, Rio de Janeiro,Brazil, have invented 4certain new and useful lm rovements 1n Means forRaising Sunken essels, &c., of which the iollowin is a speciiication.

My 'invention re ates to submarine apparatus used to raise submergedvessels or other objects.

It is designed to aiiord sinlple but eHective y and conveniently appliedtoa the object such manner that the several parts are held iirmlyagainst slip or displacement.

The invention consistsin the combination with suitable caisson-buoys,each provided which the harness cables or chains are atupon the tached,and toggle guide-clutches ort of the caisson-buoys fory the lateral supsuspender-c ains, which allow t e caissonbuoysl to slide downward uponsaid suspender-chains, but automatically grip the same whenv any back orupward ressure is exerted by the caisson-bue s, suiis'tantiall ashereinafter described an claimed speci ically. O

in the accompanying drawings, Figure 1 represents a side elevation of aship under water with my a pliances ap lied thereto.

of iioat or caisson-buoy;

' T e caisson-buoys A A Fig'. 2 is a plan o the same;

Flg. 7 is a section upon plane lof linem n, Fig. 8. Fig. 8 is a to View of one ofthe toggle guide-clutches.

A2 may be of any desired shape and capacity, but are preferably ofcylindrical form with either flat (l) or convex (2)v ends, and areprovided' with means for dischargin water Jrom their interiors. Variouswellbe resorted to for this lrixilnpose--as7 for example, a reservoir inw 'c a gaseous iuid has been stored under high pressure, which whenreleased ejects water from the body of the caisson-buoy. i prefer touse, however,l for this purpose a centrifugal pump E, Figs..

5 and e, in conjunction wit a dynamo for operating the same. The pumpand dynamo to be raised inl own expediente may..

may be arranged in a water-tight compartment 5,'having an opening 4.-,closed by a removable door 6.

- 7 is the suction-pipe for the pump, and is the discharge-valvesituated 1n a recess eX- ternal to the caisson-buoy.

10 represents electric wires cennectingthe dynamo C .witha suitablesource of elec- 'tricity ln Figs. 5 and 6 a hollow lcoupling re resentedfor the attachment o av tube re resented by the line 12, said tube beingo suicient'strength to avoid collapse under the pressure ofexternalwater. Each caisson-bnc is thus provided with a coupling and tue for the purpose of admitting atmospheric air.

13 re resents eyelets or staples upon the caissonuoys by means of whichtheyx may be chained together, as indicatedin 4gs. 1l and 2. 14represents automatic. tog le guideclutches' attached to the sides of t ecaissonbuoys, said automatic clutches being shown in detail inFi s. 7and 8 and bein 'used for' the purpose o englagement with t ceguidechains 15, by Whici the caisson-buoys wheny immersed are conductedto their respective positions uponor with relation to them'iblect,

to be raised, the lower ends of said". ide-ff chains 15 bein attached bymeans reyes lets 26 to the eel or supporting-plates 2,4. The keel orsupporting plates 24 are cou led together by chains 25. Fromfthe keel-pates 24 the lguide-chains 15 pass upward between the toggle-arms 17,Figs. 7 and 8, each eil which 1s pivotally supported upon a fixed pin18, projecting from a plate secured ri idly to the side of acaisson-buoy. The togg -arms 17 are of such length and are so arrangedthatu they are free to field u ward to admit of their passage over theguide-chain 15 during the descent of the caisson-buoy, but pinch andhold the chain irmly when the caissonbuoys strain u ward, therebyutilizing the portions of gui e-chains 15 below the autovmatic clutches14 as lifting-chains.

H represents a water-ti ht compartment.'-

contaimng a supply ci car uret oi calcium,-

s'aid compartment being provided with a door 20. l 21 is a oat-cock forregulating the admission of water from the interior ofthe caissonl buoyinto the compartment H, and 22-is a lvalve, for admitting into theinterior of said caisson-buey the gas produced by theI coni I 'then .theWater in these caisson-buoysAis exhausted by pumps or other means. Thecaisson-buoys A then operate to straighten out the ship and lessen thepressure of the same against the sea-bottom, thus permitting the placingof the keel-seats or supportingplates 24, the latter when locatedeingsecured in osition by means of the chains 15 passing tlirough theaperture 16, provided inD the caisson-buoys A. To the eyelets 26 of thekeel-plates or supports are then secured the ends ofthe chainsl 15, andalong these are A caused to descend the caisson-buoys A, filled withWater, to the sides of the .shi near its keel, the automatic clutches 14inally securingthe caisson-buoys A in position with the lower portionsof the chains l5 taut. The Water containedin the buoys A is thenexhausted in order that they may develop their full lifting -capacity inconjunction With the buoys A to raise the Vessel to the surface.

` What l claim as rn invention, and desire to secure by Letters atent,is-

1. The 'combination with caisson-buoys each provided with means for,exhausting Water therefrom, of automatic clutchrides upon saidcaisson-huoys, guiding and `fting chains passing .thro'ughsaid'automatic clutchides, supportingplates attached to the oWer ends ofsaid guiding and lifting chains and couplingr chains connectingadjoining supporting-p ates, for the purpose described.

2. ln apparatus of the character designated, the combination of thecaisson-buoys A and Al ,each provided with means for eX- 'hausting Watertherefrom, automatic clutchguides 14 secured to the sides of thecaissons A, guiding and lifting chains 15 passin through said automaticclutch-guides an attached at their loWer ends to supportingplates 24,coupling-chains 25 -connctingsaid supporting-plates, and guiding andlifting chains 15, attached to said supporting-plates 24 and passingthrough the calsson-buoysA, substantially 1n the manner and for the.purpose described.

In testimony whereof Ihave hereunto set my hand in presence of tWosubscribing Witnesse's. 'i
